Tyre Pressure: How to Check It

Tyre Pressure · Posted by: Mobile Tyres 2 U · 26th February 2021

It doesn’t matter how high-performance your vehicle is, if your tyres aren’t maintained properly, then this performance can’t translate to speed and control while out on the road. Sure, your tyres might look fine – you can clearly see the tread pattern and there’s no visible damage – but when was the last time you actually checked the pressure? 

Your tyres don’t need to be visibly flat to have low pressure, something which many motorists don’t seem to understand. With this in mind, this month, the Mobile Tyres 2 U team are going to break down exactly how to check the pressure of your tyres, so you can get the most out of your car’s performance.

Get a pressure gauge

Before you check your tyre pressure, you’re going to need a pressure gauge. You should be able to get a good one for under £20 online. However, if you would rather save a bit of cash, you can always head down to your local petrol station where you should be able to find a gauge and a pump on the forecourt.

Checking the pressure, step by step

1. Check the PSI recommended by the manufacturer – there’s no use in checking your tyres if you don’t know what the recommended pressure should be, so make sure that you do this first. You should be able to find this information in your vehicle’s handbook.
2. Attaching the gauge – first, remove the valve cap from a tyre. Once it’s off, press the gauge onto the stem of the valve until the hiss goes away and the device provides a reading. Once you’ve got it, write it down and repeat the process for the other tyres.
3. Letting air out – so you’ve got the reading, now what? Well, if the gauge indicates your tyres are overinflated, you’re going to need to let some air out. You should be able to find a metal pin inside the valve stem, press it in with a screwdriver until you’ve let out enough air.
4. Refilling air – if you haven’t checked the pressure of your tyres in a long time, the likelihood is they will be underinflated, meaning you’re going to have to refill them with air. To do this, you’re going to need a pump. Press the pump hose onto the valve stem and start filling the tyre with air until you see the right reading on the gauge. It’s that simple!

If, when checking the pressure of your tyres, you get a low PSI reading as well as noticing some damage to the surface of your tyre, it could well be the case that you need them replaced.  However, this doesn’t mean you need to go to your local garage, just give Mobile Tyres 2 U a call who will be able to replace your tyres right there on your driveway.
